I’ve been listening to the breadboarded versions of the Duelund crossovers on the Westminster Royal SE’s this week, in the evenings after I got home from the office, and man, what a revelation! I decided to take today off and get some more work done on Duelund-WRSE Project.  Before getting started on what I need to [...]

I just finished up installing the other Duelund crossover on the right Westminster Royal SE, so now I have a stereo pair up and running. Not bad progress for a weekends worth of work! I was able to improve the layout of the right channel pair of Duelund crossovers and make it quite a bit more [...]

I was chatting with Frederik Carøe in Denmark this morning by email while waking up with some nice hot coffee (medium roasted Kenya beans). I wanted to give Frederik an update on how things are going with the Duelund-WRSE Project, and ask Frederick for any suggestions he might have on improvements and such.   I [...]

Stephaen sent an early morning email: “I’m going to stop at the El Fat Cat Grill taco truck and get us lunch, and I’ll meet you and Pete at your place at noon.” While the El Fat Cat Grill is actually a taco truck, referring to it as ‘taco truck’ is like referring to the [...]

In the Duelund-WRSE Crossover Project we are using the Duelund Coherent Audio Silver / Carbon resistors exclusively in the circuits (seen on the far right in the photo below). Resistors are inherently simple electrical devices that are used to control the flow of current in a crossover circuit by providing a constant resistance that does [...]

I’m up early this morning drinking coffee and listening to the Beatles’ Rubber soul LP from the new box set through the Sophia Electric 91-03 300B integrated amplifier. Particularly considering the 91-03 hasn’t even been playing for an hour, its sounding really good. Very natural, sweet, and musical. Today Pete Riggle & Stephaen Harrell (6Moons) are coming over to [...]

Today’s Fresh Catch is the new Duelund Coherent Audio CAST Mylar Capacitor. For those of you who have been following the developments of the Duelund-WRSE Project, where we are building custom outboard crossovers for the Tannoy Westminster Royal SE loudspeakers using the state-of-art Duelund Coherent Audio CAST components, you know that Frederik Carøe created a [...]

I can’t think of a better way to spend a Saturday than eating wood-fired pizza, drinking some nice Italian & Argentinian wines, and laughing & talking with Pete Riggle and Stephaen Harrell while breadboarding the Duelund-WRSE crossovers. We started with a full set of the Duelund CAST components for the crossover. (seen below sitting on [...]

Pambos just sent me an email with an excellent suggestion about posting photos of peoples’ Westminster Royal or Canterbury loudspeakers in their listening rooms, based on the interactions we’ve had for upgrading the crossovers on those two speakers. We’ve got a lot of Tannoy owners that drop by, and I didn’t want to exclude anyone, [...]

In my last post I described all of the attention to detail that goes into producing the hand-made & labor intensive Duelund CAST capacitors, and in this post I want to tell you about the Duelund CAST Air Core Inductor that we will be using in the Duelund-Westminster Project as shown in positions L1 and L2 below. An inductor [...]
